TYP E-wRl'l'l NG MACHINE.

To all whom itmcty concern.-

Be it known thatI, CHARLES H. SHEPARn,

a citizen of the UnitedStates, and a resident of the borough of Brooklyn, city'of New York, in the county of Kings and State of New York, have invented certain new and useful Im provements in Type-Writing Machines, of

which the following is a specification.

This invention relates to ink-ribbon spools, such as used in type-writing machines. V

The'object of the invention is -'to provide improved means for 'attachingthe ribbon to} thespool." a

The inventionconsists in'certain combinations of devices and features of construction, all as will be fully hereinafter set forth, and particularly pointed out in the concluding claims. 1 V

In the accompanying drawings, Figure 1 is an edge view of a spool provided with my improvement, the ribbon-clasp being slightly raised, so as to disclose the needle-points upon I which the ribbon is impaled. Fig. 2 is a cross-section of the spool,showing the ribbonclasp swung away from the core and one end of a ribbon placed over the latter. Fig. 3 is an edge View of the devices shown at Fig. 4. Fig. 4 is a side view,a portion of the head of the spool being brokenaway. Fig. 5 is a perspective view of a clasp detached from the spool. Fig. 6 is a cross-section of a spool, showing a modified construction of clasp.

' In the several views similar parts are designated by similarcharacters of reference.

The head or front flange of the spool is designated as 1, the rear flange as 2, and the wooden core as 3. Between the flanges is swung upon pivots 4 a clasp consisting of opposite arms, 5, a cross-piece 6, and anextended finger 7, whichnormally curves closely its tip a flattened or recessedpart 8, formed upon the periphery thereof about diametricthe clasp in 5 working position.

to form a ledge, which is provided with a row ally opposite from the hinge 4, so as to lock The crosspiece 6 of the clasp or bail is provided with a portion 9, which extends longitudinally thereof and is bent at an angle thereto, so as the arm'so and extends through an arc-shaped resent N6. 700,445, dated Ma 20, 1902.

of perforations or notches10. Inthe peri n. 50; cry of the core is cut a longitudinal-recess 11, 1; adaptedto the clasp and having an abrupt a face 12, against which the ledge 9 bears, Projecting from the face 12 isa rowofim-i i 1 paling pointsor needles -13, opposite the. notcheslO in the clasp. v a s a i The end of theribbon isplaced upon the core .so as to coverthe recessjll, 'asf illus trated at'Fig. 2. Then the clasp is swung to, 7 its "seat-upon the core by. means of a finger piece or pin 14, which is formedquponone of,

perforation 15, fo'rmed 'in one head of the. spool,"so as to be convenient to the operator. The ledge 9 upon contactingwiththe'ribbon A doubles the latterinto the recess llan'd irnpales it upon the needles 13, Preferably j theribbon is also firmly clampedbetween the I ledge and the opposing face '12 of the recess. 1 11, as illustrated "at Fig.4. The finger 7 s, springs outwardly when slipping over the edge of the recess Sand -then snapsinto said recess, (see Fig. 4,) thereby securely retaining the clasp in working position and preventing accidental detachment of theribbon. In or- 7 5 I der to detach the ribbon, it is, only necessary- I to press the handle 14 outwardly, whereby the clasp is swung to the Fig. 2 position,1 thereby releasing the ribbon,;which may be withdrawn fromt-he iinpaling-needles. 8'o

It will be seen that the arms5 are thin and 1' f he flat against the inner sides of thespool v flanges and that the cross-bar 6, as well as the. finger 7, which forms a continuation thereof, are also thin and hug closelythe periphery of the spool-core, sov as toleave practically the same amount of space for the ribbonla's if noclasp were present. I

Preferably the arms5,cross-piece' 6,]ledge", 5 9, and finger7 are stamped fromiajsinglej go piece of sheet metal. Thus itwillfbe seen: l 3 that by the employment of an inexpensively manufactured device the ribbon'may be read: i1 attached to the spool or detached there-j I from, as desired, without risk ofsoiling the 5 fingers.- F Referring now to Fig. 6, it willbe seen that the needles 1 3 are omitted. One or mo teeth 16 are formed upon the cross-piece 9 of the clasp or bail, and a longitudinal recess or undercut 17 is formed at the lower part of the abrupt face or abutment 12. lVhen a ribbon is to be attached, the clasp is swung to the Fig. 2 position and the ribbon placed over the recess 11. Then the clasp is swung back to the Fig. 6 position, the ribbon being doubled into the undercut 17 by the teeth 16, which also indent or impale the ribbon, so that the latter becomes firmly attached to the spool.

What I claim as new, and desire to secure by Letters Patent, is

1. In a ribbon-spool, the combination with a pair of flanges and a core, of a bail arranged between the spool-flanges and pivoted thereto, said bail having a cross-blade or ledge 9 provided with notches or openings, a recess in the core having an abrupt face opposed to said ledge, and impaling-needles projecting from said abrupt face opposite said notches or-openings.

2. Ina ribbon-spool, the combination with a pair of flanges and a core, of a clasp consisting of opposite arms 5 which are pivoted at their outer ends to the flanges, a cross-piece 6, and an extended finger '7 which curves around the core of the spool and is adapted to retain the clasp in working position.

3. In aribbon-spool, the combination with a pair of flanges and a core, of a clasp consisting of opposite arms 5, which are pivoted at their outer ends to the flanges, a cross-piece 6, and an extended finger 7 which curves around the core of the spool and is'adapted to. retain the clasp in working position, said core havinga recessed portion 8 formed in its periphery for engaging the tip of said finger.

at. In a ribbon-spool, the combination of a pair of flanges, a core, a bailcomprising a cross-piece and arms 5 whose outer ends are pivoted to the flanges, a series of openings in said cross-piece, and a series of impalingpoints fixed in the core opposite said openings.

5. In a ribbon-spool, the combination with a pair of flanges and a core, of a clasp arranged between the flanges and comprising a crosspiece and arms whose outer-ends are pivoted to the flanges, said cross-piece having a portion 9 which is bent at an angle to the crosspiece so as to form a ledge, a row of notches or openings 10 formed in said ledge, a longitudinal recess formed in the spool-core, and a series of impaling-points fixed in said recess opposite said notches or openings.

6. In a ribbon-spool, the combination with a pair of flanges and a core, of a longitudinal recess formed in the core and having an abrupt face, and a clasp pivoted upon the spoolflanges and having a part which enters said recess and cooperates with said abrupt face to clamp the ribbon.

7. In a ribbon-spool, the combination with a pair of flanges and a core, of a ribbon-clasp comprising arms 5, cross-piece 6,1edge 9, and locking-finger 7, all formed from a single piece of sheet metal, and means upon the core for cooperating with said clasp to hold the ribbon.

8. In a ribbon-spool, the combination with a pair of flanges and a core, of a ribbon-clasp comprising arms 5, cross-piece 6, ledge 9 and locking-finger 7, all formed from a single piece of sheet metal, and means upon the core for cooperating with said clasp to hold the ribbon, one of said arms 5 having a fingerpiece let which projects through an opening 15 in the contiguous spool-flange.

9. In a ribbon-spool, the combination with a pair of flanges and a core, of a bail-like clasp whose opposite arms are pivoted at their outer ends to the inner sides of the flanges, means upon the core for cooperating with said clasp to hold the ribbon, and a finger-piece upon one of the bail-arms which projects through a slot formed in the contiguous spool-flange.

10. In a ribbon-spool, the combination of a core havinga recess, an impaling-pin projecting into said recess, and a device for carrying the end of the ribbon into said recess an( impaling it upon said pin.

11. In a ribbon-spool, the combination of a core having a recess, an impaling-pin projecting thereinto, and a swinging bail-like clasp adapted to carry the ribbon into said recess and force it upon said pin.

12. In a ribbon-spool, the combination of a core having a recess, aswinging clasp adapted to carry the end of the ribbon into said recess, and an impaling point or points for holding the ribbon in said recess.

13. In a ribbon-spool, the combination of a core having a recess, a swinging clasp adapted to carry the ribbon thereinto, an impaling point or points adapted to hold the ribbon in said recess, and means for holding the carrying portion of said clasp within said recess.
